Modelling the acoustically excited plane jet

Abstract

Currently there is not any existing lumped model which models flue instruments with the desired accuracy. In this paper we investigate an important piece of the lumped models, the receptivity of the jet, which models the forcing of the acoustic resonator on the jet. Previously at the Department of Hydrodynamic Systems a model was developed, with which the effect of the acoustic forcing in an incompressible flow can be taken into account. We compare the results of the model with measurementsfrom the literature and analyse the differences in detail.
